SV Sangle, NE Jayewar and DR Kadam
The field experiments were conducted during Rabi 2018-19 to evaluate the effect of seven newer insecticide molecules viz., sprofenophos 50 EC@ 30 ml, indoxacarb 14.5 SC @ 8.5 ml, emamectin benzoate 5 SG@ 4 g, spinosad 45SC @ 4 ml, thiamethoxam 12.6 + lambdacyhalothrin 9.5@ 2.5 ml, chlorantraniliprole 18.5 SC 3 ml and flubendiamide 49.35 SC @ 2.5 per 10 lit. of water respectively. Among the insecticides spraying, emamectin benzoate 5 SG was most effective treatment over control followed by chlorantraniliprole 18.5 SC, flubendiamide 39.35 SC, indoxacarb 14.5 SC, thimethoxam 12.6 + lambda cyhalothrin 9.5 ZC, spinosad 45 SC and profenophos 50 EC. The highest yield was recorded in the treatment emamectin benzoate 5 SG @ (42.5 q/ha) followed by chlorantraniliprole 18.5% SC (40.01 q/ha), flubendiamide 39.35 SC (38.5 q/ha) and thimethoxam 12.6 + lambda cyhalothrin 9.5 ZC (37.6 q/ha).
